T N e t D E S I G N
McQ designed TNet to optimize sensor communications. Sensor target detections and images must be delivered to the user fast and very reliably. Sensors and communication units also need to receive command and control information from the user as well as message acknowledgement for guaranteed delivery. The
TNet design insures inbound target detections messages are delivered instantaneously through the
Repeater chain and outbound messages are delivered in a timely manner. Because the
Sensors and Repeaters are battery powered, very low power consumption has been designed into the network. The TNet design uses a Mesh Ad Hoc
Network architecture. The
Repeaters and Base
Stations keep track of every component they can communicate with,
“neighbors”, and route message traffic automatically to all units.
TNet is a very flexible and efficient sensor network solution.
McQ developed a terrestrial RF wireless network designed specifically for unattended ground sensor applications. This network relays the sensor information over terrain that precludes an RF line of sight path from the sensor to the user. TNet is a self forming RF network that makes it easy for the user to quickly set up in the field. TNet is designed to maintain very low power consumption of the battery powered sensors and repeaters.

TNet allows a user to quickly set up the sensor network in the field. The user can select one of ten network channels for each sensor network. Each TNet unit can act as a Repeater or as a Base Station. One unit is configured as the
Base Station and one or more units are configured as Repeaters to reach from the sensors to the Base
Station. The TNet units recognize other units on the network channel, automatically route the message traffic to the Base
Station, and manage the command and control messages so they are delivered to the intended recipient. The Base Station unit connects via Ethernet to any IP network for distribution to the map based sensor system user interface.
